Based on a popular manga, the film is a tender coming-of-age love story set deep in Japan's countryside. When eighth grade cool guy Hiromi transfers from Tokyo to a small elementary/middle school with only six kids enrolled, wholesome and honest Soyo becomes enthralled with his sophisticated world.
Twelve years after their beloved eldest son, Junpei, drowned while saving a stranger's life, Kyohei and Toshiko welcome their surviving children home for a family reunion. Younger son Ryota still feels that his parents resent that he isn't the one who died; his new wife, Yukari, is awkwardly meeting the rest of the family for the first time. Daughter Chinami strains to fill the uncomfortable pauses with forced cheer.
Several years after Shuzo settled his wife’s birthday-surprise divorce proposal (What a Wonderful Family, 40th), the Hirata family faces new problems. Ignoring his family’s worry that he is too old to drive, Shuzo takes his old schoolmate for a spin after carousing. Soon, a new disturbance arises for the Hirata family. Veteran director Yamada Yoji continues his comedy about the “perfect“ Japanese family turned upside down in chaos, laughters and understanding. This time, with an additional taste of death.
At the Hirata home, three generations of their family live together. A crisis ensues when one afternoon, housewife Fumie falls asleep and wakes up to find a thief has stolen her secret money she kept hidden in the refrigerator.
